I haven't seen any reporting that the Marines conducted any further testing on the M18. Presumably the Marines benefited from the rather quiet reliability improvements made to the M18 after initial batches demonstrated reliability issues during Product Verification Testing. The XM18 actually exceeded the reliability of the XM17 in the second round of PVT after the "adjustments to the magazine spring, magazine follower, slide geometry, and the internal components".

No idea but I'm curious as well. SIG has been tight lipped about deficiencies revealed in military testing that resulted in manufacturing changes (to include the drop-safety episode). I haven't seen any details on the changes beyond the described "adjustments to the magazine spring, magazine follower, slide geometry, and the internal components" in the DOT&E report.
Are there new magazine followers and springs out for the 320? To be fair, updating a follower design seems like a nearly continuous process for manufacturers (what iteration is Glock up to now?). Slide geometry and internal components seem more significant changes.

Has anyone seen, or heard a second-hand account of, a double ejection on a P320? I still have a hard time imagining that happening dozens of times without causing a stoppage.
